Lane departure prevention

Using information from the 1 camera, the function triggers corrective action on the vehicle steering system when a continuous or broken line is crossed or when approaching the roadside (divider, barrier, pavement, embankment, etc.) without activating the direction indicator lights.
Depending on the setting, in the event of crossing a broken line without activating the direction indicator lights, the function:
  • warns the driver without corrective action on the steering system;
or
  • performs corrective action on the steering system.
Tip
You can retake control of the vehicle at any time by operating the steering wheel.

Location of camera 1

Make sure the windscreen is not obscured (by dirt, mud, snow, condensation etc.).
WARNING
This function is an additional driving aid. This function is not under any circumstances intended to replace the due care and attention of the driver, who should at all times be in control of the vehicle.

Activation/deactivation

From the multimedia screen 2

Please refer to the multimedia instructions for more information.

From the "My Safety" switch 3

  • To deactivate the function, if it has been deactivated from the "custom" mode of the "My Safety" MY SAFETYfunction, press switch 3 twice. The warning light is displayed in yellow on the instrument panel.
  • To reactivate the function, press the 3switch once. Warning light comes on the instrument panel.

Operation

When the function is activated, the or and the left-hand and right-hand line indicators 4 are displayed in grey on the instrument panel.
The function is set to emit a warning or to operate when the vehicle speed is between approximately 40 mph (65 km/h) and 112 mph (180 km/h) and if the or warning light and the left-hand and right-hand line indicators 4 appear in white.
The function is in operation if the vehicle
  • approaches a roadside without activating direction indicators;
  • crosses a continuous line without activating the indicator lights;
  • crosses a broken line without activating the direction indicators, if the "operation on broken line" setting is selected.
In these cases:
  • the function triggers an action on the vehicle's steering system to correct the vehicle trajectory;
  • the or warning light and the indicator 4 on the side of the breached line changes to yellow on the instrument panel.
If the corrective action on the steering system is not sufficient, the or warning light and the indicator 4 on the side of the breached line change to red on the instrument panel, accompanied by a vibration on the steering wheel.
When the "Operation on broken line" setting is not selected, the function sounds the alarm if the vehicle crosses a broken line without activating the indicator lights, and there is no roadside close enough to the line.
In this case, the function warns the driver:
  • by a vibration in the steering wheel;
and
  • the or warning light and the indicator 4 on the side of the breached line turns to red on the instrument panel.
Note: on bends, the function allows for slightly cutting the bend.

Special cases

"Keep control" Warning
  • If the system is operating and does not detect any activity on the steering wheel, the "Keep control" message appears on the instrument panel accompanied by a beep and, depending on the vehicle, the warning light appears in yellow until the driver has regained control of the vehicle.
  • If the system has been in operation for too long, the "Keep control" message appears on the instrument panel accompanied by a beep and depending on the vehicle, the warning light appears in yellow accompanied by the indicator 4 on the side of the line concerned until the driver has regained control of the vehicle.
Tip
You can interrupt the trajectory correction at any time by moving the steering wheel.

Vehicle fitted with "Active driver assist"

If the "Lane centring" function is activated at the same time as the "Lane departure prevention" function, the display of the warning light will vary as follows:
  • the "Lane Centring" function is in operation: the green warning light replaces the white or grey or warning light on the instrument panel. Thus, you are informed as a priority of the status of the function "Channel centriing";
  • the "Lane Centring" function is put on standby and the "Lane Departure Prevention" function is neither ready nor in operation: the grey warning light replaces the white or grey or warning light on the instrument panel. Thus, you are informed as a priority of the status of the function "Channel centriing";
  • the "Lane Centring" function is put on standby while the "Lane Departure Prevention" function is ready or in operation: the or warning light is displayed in red or in yellow on the instrument panel. Thus, you are informed as a priority of the status of the function "Lane departure prevention".
In any case, you are informed at all times of the status of the function when it controls the steering system of your vehicle. The most useful information is always displayed.

Temporary unavailability / function disabled

The system is temporarily unavailable or disabled when:
  • very fast lane departure;
  • driving continuously on a line;
  • approximately four seconds after changing lanes;
  • tight bends;
  • impaired visibility;
  • one of the direction indicators is activated;
  • activating the hazard warning lights;
  • engaging reverse gear;
  • strong acceleration;
  • the lane width changes;
  • operation of the Electronic Stability Control system;
  • operation of the anti-lock braking system;
  • the active emergency braking system is triggered;
  • intervention of another function that controls the steering system, such as the "Lane Centring" function.
If the function is unavailable, the or warning light and the left-hand and right-hand correction indicators 4 appear in grey on the instrument panel.
If the front camera is obscured, the "Front camera without visibility" message is displayed on the instrument panel. Clean the area where the sensors are located

Automatic deactivation

The function is automatically deactivated when:
  • The vehicle dynamics control system is deactivated;
  • The electronic stability system is malfunctioning;
  • The anti-lock braking system is malfunctioning;
  • a towbar is electrically connected to the trailer hitch socket;
  • the warning light is displayed.
When the function is deactivated, the warning light is displayed in yellow on the instrument panel.

Settings

To access the multimedia screen function settings 2, refer to the multimedia instructions:
  • " Operation on broken line": use this setting to select the response of the function if the vehicle crosses a broken line without activating the direction indicators:
    • selected setting: the function may trigger an action on the vehicle's steering system to correct the vehicle trajectory;
    • setting not selected: the function can warn the driver by means of a vibration at the steering wheel without correcting the vehicle trajectory.
  • "Vibration": adjust the steering wheel vibration for the "Lane departure prevention" function;
  • "Lane exit anticipation": adjust the line detection sensitivity level. To do this, select:
    • Late”: line detected upon crossing;
    • Standard”: line detected on approach;

This function is an additional driving aid. This function is not under any circumstances intended to replace the due care and attention of the driver, who should at all times be in control of the vehicle.
System servicing/repairs
  • In the event of an impact, the camera alignment may be changed, and its operation may consequently be affected. Deactivate the function and consult an authorised dealer.
  • Any work in the area where the camera is located (repairs, replacements, windscreen modifications etc.) must be carried out by a qualified professional.
Only an authorised dealer is qualified to service the system.
In the event of system disturbance
Some conditions can disturb or damage the system's operation, such as:
  • windscreen obscured (by dirt, ice, snow, condensation etc.);
  • a complex environment (tunnel, etc.);
  • poor weather conditions (snow, rain, hail, black ice, etc.);
  • poor visibility (night, fog, etc.);
